Find my old post or read my website. I think I put in there the exact clearcoat I used. You don't want gloss, and the stuff I used was preferable to semi-gloss. The glossier they are, the more your imperfections will show.
Most Auto parts stores can get VHT on their next order, no extra cost to you. That'* how I got my can and Jseabert'*. Now we have a store that stocks it on the shelf.
